To all whom it may conceive.

Be it known that I, PHIL'IP Hens, a citizen of the United States, residing at Peoria,

- in the county of Peoria and State of Illinois,

have invented certain new and useful Improvements in P ulverizing-Harrows; and I do hereby declare'that the following is a full,

. clear, and exact description of the invention,

which will enable others skilled in the art to which it appertains to make and use the same. My invention relates to certain new and us'efulgimprovements in pulverizing-harrows by means of which a barrow is provided having particular and special features of construction which render it particularly well fitted as a pulverizer and other detail features that facilitate particularly the removal or transportation of the harrow to andfrom dif- Ierent places;

More particularly my invention relates to atoothed harrow adapted to drag over the I surface of the'ground; and the principal feature in the invention therein consists in the particular manner in which the teeth are constructed, the toothed stem consisting of a rectangular body secured to the main frame,

' to which all of the separate teeth are attached,

the lower end of the tooth being expanded and tapered into shovel form and grooved in a particular manner 'at the rear of the blade or shovehas will hereinafter" be more particularly shown and described. Also iny invention includes certain raised frame parts supported on the topof the main narrow-framework, which serve as runners to support the harrow when it is inverted orturned upside down, which, as before stated, facilitates the removal of the barrow from one place to another, the harrow being dragged along upon the runners. The upright frame parts which serve as runners also provide handholds for the operator when the harrow is in use, which enables him to raise it or turn it from side to side conveniently.

- That my invention may be more'fully understood, reference is had to the accompanying drawings, in which- 1 Figure I is a plan View showing the top 0 the harrow-fr'ame and shows it in position as it isfworked in the field, also showing in dotted lines the manner of hitching to the harrow when it is being dragged on the runners.

Referring to Fig. 3, g" is the blade portion of the tooth and is formed by flattening and curving the end of said tooth, thus forming the small blade or shovel. Opposite the face of the blade and at the rear thereof is the groove 9 (shown in both views of Fig. 3,) provided for the purpose of equalizing the resistance to the passage of the blade through the ground, to adaptit for clearance which insures perfect scouring and no clogging. .This particular groove, which enters into the construction of the tooth, is one of the main features thereof and is essential to the perfect working of th'esame.

-The above are the main features. in the construction of the harrow proper.

G is a footpiece constructed similar to the tooth and attachedto the framework in the same manner, but is bent at right angles at its lower" end and flattened, adapting it to extent at its forwzii 1 end. This footpiece is placed at the corn er of the harrow from which it is dragged over the ground. This footpiece prevents the teeth from penetrating too deeply in the ground and offsets the tendency to constant downward draft of the barrow.

In the drawings, 1) D are sled-runners, the same being curved at their forward ends and attached to the framework and at their rear portion are supported upon the frame-pieces f f, the sled-runners extending beyond the frame-pieces f f to provide handholds.

I desire to call tttention to the forward end of the harrow as it is shown in Fig. 1 and to note'the fact that the position of the barrow there shown is the position of the harrow when it isheing dragged in the field. The

' chain a, connected to the small ring E, indioates the p'oiutwhere the draft is applied. The ringE is not fixedgtt this point, but may slide from one side of the herrow tothe other, which is a, conveuientconneotion, as the ring being soeonnected that it may shift readily facilitates turning the barrow and also adapts 'the ring to be shifted from its norinal draft position when it is working to the hooks c, which is the connection made when the harroW is inverted for the purpose of dragging it upon the runners D, this adjustment being made without detaching the ring: E, it being always attached to the harrow, with no chance for its being lost.

The barrow, as shown and described'in the drawings, When applied for practical use in the field serves a. purpose beyond. that ordinarily reqni red of the ordinary harrow, which is inerelyto pnlverize and level the immedi-.

ate surface of the ground, but serves the further purpose of a disk pulverizer so far as penetration and loosening of the ground is concerned, and also serves every purpose of a. cultivator when used for like purposes; but it does not ridge the ground as the disk pulverizer and the cultivator, which requires the application of a harrow to level itbefore seeding, but leaves the 'groundas level as the ordinary narrow and loosens it as effectually and as deeply as the disk pnlverizer or the cultivator.

' Having thus fully described my invention, what I ,olaini, and desire to secure by Letters Patent, i-s- 1. In apulverizing-harrow,-the combination with the framework thereof of a series of herrow-teeth supported therein, each formed of a vertical stern and the lower end thereof expanded and forwardly curved to form a. small shovel and provided with a groove at the back of the shovel, and a footpiece set in the forwardpart of the framework adapted to drag on the surface of the ground, substantially as described and shown.

2. In a pulverizing-harrow, the combination, with the framework consisting of the main outside frame A, the eross f'rame parts 0, C, and the diagonal frame-piece B, of the harrow-teeth F, supported therein'n'nd expended and forwardly curved at their lower ends to form the smell shovels g, provided with groove at the hack of the shovel, and the footpiece G, substantially as described and shown. e s

3. In a. pnlverizing-harrow, the combine tion, with the framework consisting of the main frame part A, the cross-pieces'G, O, and the diagonal frame-piece B, ofthe her: row-teeth F, securely attached to the framework and expanded and curved at their lower ends to form the smell sl'iovels g, ha-vingthe groove 9 at the rearof the shovels; the footpiece G, secured to the framework and the :runners D, D,'seeur.ed to the upper part of the barrow-framework, substantially as described andshown.

. In testimony-whereof I affix my signature in presence of two witnesses.
